When you choose to do temple plastic surgery with rich autologous fat, you will worry about the survival rate of its fat. As we all know, the survival rate of autologous fat transplantation is generally low. How to improve its survival rate? Changsha Sanhe plastic surgery experts help you. First, pay attention to the choice of suction method, try to use empty needle liposuction, and the negative pressure should not exceed 0.05MPa. The method of liposuction during surgery directly affects the result of surgery. Because, in the process of surgical aspiration, some cells will inevitably be damaged and destroyed. The greater the degree of injury, the fewer living cells and the lower the survival rate. Most scholars advocate empty needle liposuction, and its negative pressure is less than 0.05MPa, which can reduce the damage to cells. If other non-invasive techniques are used to suck fat, it is best to use a thin tube below 4mm as a straw. Because the whole operation was carried out in the subcutaneous fat layer without big blood vessels and nerves, all the fat was extracted, and the patient basically had no bleeding and pain. Second, try to choose thigh fat with high fat activity. It is found that the activity of LPL in different parts of human body is different. It was found that the lipoprotein lipase activity in thigh adipose tissue was higher than that in other parts. LPL activity is high, which is beneficial to the regeneration and survival of transplanted adipocytes. The LPL activity of thighs and buttocks is the highest, followed by lower abdomen and upper abdomen. According to this study and the deep fat distribution in these parts, the lower part of trunk should be the first choice for autologous fat breast augmentation fat transplantation. Third, when the temples are full, try to spread the fat into multiple points. The principle of temple fullness is to disperse fat into multiple points and disperse them evenly in the recipient tissue. The injection amount of each acupoint should not exceed 1ml to avoid a large amount of fat concentrated in a certain part, and massage should be performed after injection. This method is small in size and scattered in parts, which is easy to establish the blood supply of the implant and is beneficial to the survival of fat particles. Fourth, the purification treatment of fat particles to extract high-quality fat collected fat particles should be washed and filtered with 4-degree normal saline to wash away damaged fat cells, fat droplets and blood. Special attention should be paid to aseptic operation during purification; The storage time of fat particles in vitro should also be reduced as much as possible to improve the survival rate of fat cells.
